Please refer to RSA Knowledge Base Article 000030327 -- Artifacts to gather in RSA Identity Governance & Lifecycle to find the location of the aveksaServer.log file for your specific deployment if you are on a WildFly cluster or a non-WildFly platform. The aveksaServer.log may also be downloaded from the RSA Identity Governance & Lifecycle user interface (Admin > System > Server Nodes tab > under Logs.)
